详解数据库基础操作及实例

     废话不多说，直接上代码，注释写的比较清楚，大家参考下，

 示例代码：

/**
* 插入一条DB对象
*/
public static void addDBObject(DBCollection collection,BasicDBObject object){
collection.insert(object);
}

/**
* 根据id查询DBObject
*/
public static DBObject getDBObjectById(String value) throws UnknownHostException, MongoException{
dbc = getDBCollection("company", "users").find(new BasicDBObject("_id",new ObjectId(value)));
DBObject ob = null;
int i = 0;
